Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Formula: C6H14N2, Which mentioned a new discovery about 20439-47-8
With benzyl group as a linker, trans-(1R,2R)-diaminocyclohexane was incorporated into the framework of mesoporous silica through one-step co-condensation of tetramethoxysilane with N,N?-bis[4-(trimethoxysilyl) benzyl]-(-)-(1R,2R)-diaminocyclohexane using cetyltrimethylammonium bromide as a structure-directing agent under basic conditions. All materials were fully characterized by X-ray diffraction, N2 sorption isotherms, transmission electron microscopy, and 13C and 29Si cross-polarization magic-angle spinning nuclear magnetic resonance spectroscopy. Coordinated with [Rh(cod)Cl]2, the material exhibited a TOF up to ?414 h-1 with 30% ee for the asymmetric transfer hydrogenation of acetophenone. Various ketones were hydrogenated with different activities and enantioselectivities. An enantioselectivity of about 61% ee was observed in the case of 2-acetylnaphthalene. Moreover, a comparison of the catalytic properties of the materials with benzyl and propyl groups as linkers indicates the importance of the rigidity and electron-withdrawing ability of the linker in the high reaction rate of the catalysts.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Formula: C6H14N2, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 20439-47-8
